Dividing small number by a large number?

Hi, I'm running a while loop within which I'm dividing integers (e.g 20, 40, 80) by 1e6 , but I keep getting '0' as my answer for each run of the while loop. What can I do to obtain as many values as possible to the right of the decimal point ? I've tried the 'format' method, but it doesn't seem to be working.

Any help is much appreciated.

Thanks!

by default, Matlab uses double to store numbers. if for some reason you are using int32 variables in your program, you could cast them to double:

double(a)/1e6

in case is of class int32. the format command only controls the way numbers are displayed in the command window. it does not effect the results
